Summary: This paper investigates the relationships between structure characteristics of project network, types of conflicts, and project success. Findings show that network centrality of project stakeholders negatively affects project success, while the effect of network density is insignificant. Network density is positively related to task conflict but negatively related to process and relationship conflict. Network centrality is positively related to relationship conflict and has negative effects on task and process conflict.

Summary: Project-based learning (PBL) is an effective pedagogy that helps students learn interdisciplinary knowledge, problem-solving skills, thinking modes, and collaborative practices. However, implementing PBL has been challenging for instructors. The emergence of PBL E-learning platforms seems to provide a solution. In this study, we surveyed and analyzed 16 PBL learning platforms in English and Chinese to understand their features, functions, and how they tackle implementation challenges. We also identified trends in PBL development and provided suggestions for platform design improvement.

Summary: The Connected Max-k-Cut Problem is an extension of the well-known Max-Cut Problem, where the objective is to partition a graph into k connected subgraphs by maximizing the cost of inter-partition edges. The researchers propose a new integer linear program and a branch-and-cut algorithm for this problem, and also use graph isomorphism to structure the instances and facilitate their resolution. Extensive computational experiments show that, if k > 2, their approach outperforms existing algorithms in terms of quality.

Summary: This paper studies a variant of the orienteering problem known as the clustered orienteering problem. In this problem, customers are grouped into clusters and a profit is associated with each cluster, collected only when all customers in the cluster are served. The proposed evolutionary algorithm, incorporating a backbone-based crossover operator and a destroy-and-repair mutation operator, outperforms existing algorithms on benchmark instances and sets new records on some instances. It also demonstrates scalability on large instances and has shown superiority over three state-of-the-art COP algorithms. The algorithm is also successfully applied to a dynamic version of the COP considering stochastic travel time.
